[Tech Breakdown] What Qualifies As ePHI On A Public-Facing Healthcare Website?
For years, healthcare organizations operated under a simple assumption: HIPAA compliance applied strictly to what happened behind the login portal—electronic health records (EHRs), patient portals, and internal databases. Public-facing websites, intended for marketing and general information, were considered safe zones.
That assumption is no longer valid.
Under recent guidance from the Department of Health and Human Services (HHS) and the Federal Trade Commission (FTC), electronic Protected Health Information (ePHI) can easily be generated on a public, unauthenticated healthcare website.
If your public website uses common tracking tools like Google Analytics, the Meta Pixel, or marketing cookies, you may unknowingly be collecting and transmitting ePHI to third parties without a Business Associate Agreement (BAA). This breakdown explains exactly what qualifies as ePHI on public-facing websites and how to protect your organization from severe compliance penalties.
Understanding ePHI in the Digital Healthcare Era
To understand how a public website can trigger a HIPAA violation, we must look at how the definition of ePHI has evolved alongside modern web tracking technologies.
What is ePHI? (The HIPAA Definition)
Under HIPAA, ePHI is any protected health information that is produced, saved, received, or transferred in electronic form.
For data to be classified as ePHI, it must meet two criteria:
- It identifies an individual (or there is a reasonable basis to believe it can be used to identify them).
- It relates to the individual's past, present, or future physical or mental health condition, the provision of healthcare to that individual, or payment for that healthcare.
The Shift: Why Public-Facing Websites Are Now Under the Microscope
Historically, public websites were excluded because they did not contain patient medical records. However, modern websites use sophisticated tracking scripts (pixels, tags, and SDKs) that capture user behavior.
When a user visits your public website to research a medical condition or book an appointment, tracking scripts capture their IP address, location, and search terms, and send this data to third-party tech companies. HHS now rules that the combination of a user’s digital identifier and their browsing behavior on a healthcare website can constitute ePHI.
What Qualifies as ePHI on a Public-Facing Healthcare Website?
On a public-facing website, ePHI is rarely found in a single, obvious file. Instead, it is created when Personally Identifiable Information (PII) is linked to Healthcare Intent.
$$\text{PII (Identity)} + \text{Healthcare Intent} = \text{ePHI}$$
1. Personally Identifiable Information (PII) / Digital Identifiers
HIPAA lists 18 specific identifiers. In the context of a public website, the most common identifiers collected by tracking technologies include:
- IP addresses
- Browser cookies and device IDs
- Email addresses (entered into newsletters or contact forms)
- Phone numbers
- Geographic location data (zip codes or GPS coordinates)
2. Healthcare Intent / Browsing Behavior
When a user interacts with your website, their actions reveal their healthcare needs. Examples of online behavior that indicate healthcare intent include:
- Searching for specific symptoms (e.g., "oncology treatment options")
- Viewing a specific doctor’s bio page (e.g., a pediatric cardiologist)
- Using an online scheduling tool to book an appointment
- Signing up for a support group or health webinar
The Core Rule: If a tracking pixel links a user’s IP address or cookie ID (Identity) to a page about a specific medical condition (Healthcare Intent), that combined transmission of data is considered ePHI.
Real-World Scenarios: ePHI vs. Anonymous Data
To help clarify this distinction, the table below outlines common interactions on a public-facing healthcare website and whether they qualify as ePHI under current regulatory standards.
| User Action on Public Website | Data Collected | Does It Qualify as ePHI? | Why or Why Not? | | :--- | :--- | :--- | :--- | | A user visits the hospital's "Careers" page to apply for a job. | IP address, browser cookie, page URL. | No | The user’s intent is employment, which is unrelated to receiving healthcare services. | | A user visits the "Visiting Hours" page of a general hospital. | IP address, browser cookie. | No | The interaction does not relate to the individual's personal health condition or healthcare provision. | | A user searches for "symptoms of colon cancer" on the hospital’s public health blog. | IP address, search query, page URL. | Yes | The search reveals potential personal health intent, and the IP address identifies the individual. | | A user fills out a contact form requesting information about bariatric surgery. | Name, email, form submission data. | Yes | The user has provided direct contact information linked to a specific medical treatment inquiry. | | A user views a map of the hospital parking lot. | IP address, location data. | No | This is general administrative information and does not reveal specific medical intent. |
The Role of Tracking Pixels and Analytics
The primary driver of ePHI leaks on public websites is the use of third-party tracking technologies, specifically Google Analytics (GA4) and the Meta (Facebook) Pixel.

How Standard Analytics Create HIPAA Risks
When a user visits a page on your site, Google Analytics or Meta Pixel automatically collects metadata to help you measure marketing performance.
- Meta Pixel matches the user's website activity to their active Facebook profile.
- Google Analytics tracks user journeys across your site using client IDs and IP addresses.
Because Google and Meta will not sign a Business Associate Agreement (BAA) for their standard free tracking tools, transmitting any data that links an individual's identity to health-related pages on your website is a direct violation of HIPAA.
How to Compliance-Proof Your Public Healthcare Website
If your organization operates a public-facing website, you must take active steps to ensure you are not inadvertently collecting and sharing ePHI.
Step 1: Conduct a Tracking Technology Audit
Identify every script, tag, pixel, and cookie currently running on your website. Use browser developer tools or privacy auditing software to see exactly where user data is being sent.
Step 2: Implement a Server-Side Tag Management System
Instead of loading tracking pixels directly in the user’s browser (client-side tracking), transition to server-side tracking.
- User data is sent from the browser to a secure, HIPAA-compliant server owned by your organization.
- The server strips away all identifying PII (such as IP addresses and cookie IDs).
- The anonymized, aggregated data is then safely forwarded to Google Analytics or other marketing platforms.
Step 3: Transition to HIPAA-Compliant Vendors
If you require deep user analytics or advertising tracking, partner with vendors that specialize in healthcare compliance and are willing to sign a BAA.
- Customer Data Platforms (CDPs): Platforms like Freshpaint or Segment can act as a compliance buffer, filtering out ePHI before it reaches non-compliant third parties.
- Compliant Analytics: Consider switching to privacy-first, HIPAA-compliant analytics platforms like Piwik PRO or Fathom Analytics that allow for complete data anonymization.
Summary of Key Takeaways
- ePHI is not limited to patient portals. It can be created on public-facing websites when a user's identity (like an IP address) is linked to their healthcare intent (like looking up a medical condition).
- Standard tracking pixels are major compliance risks. Tools like Google Analytics and Meta Pixel automatically capture and transmit ePHI if they are implemented on health-related pages without a BAA.
- Compliance requires action. Healthcare organizations must audit their websites, transition to server-side tracking, or partner with vendors willing to sign BAAs to protect user privacy and avoid costly penalties.
